Reliability maintenance and engineering

Table of contents:

Anonim

Managers and engineers in organizations have an important task according to the production and maintenance of different areas, they must be very objective by incorporating a feasibility approach as well as reliability in each and every one of their strategic and tactical plans and initiatives of the signature.

This trend is an area of ​​opportunity for different departments in the organization, including areas of plant operational systems and plant maintenance.

Reliability engineering was born as a discipline focused primarily on the reliability of an organization's production and manufacturing equipment through techniques and tools, as well as methods that help determine certain components of the system or product so that they act safely., providing the appropriate quality under optimal conditions and "on time". It is of utmost importance that organizations take care of this aspect and that they take reliability engineering very seriously, since the quality of their products determines the level of customer satisfaction and also shows the internal perspective of the company, achieving competence. and profitable in the global market.

(Wikipedia, 2018)

RELIABILITY ENGINEERING

It is a branch of engineering whose objective is the study of equipment failures, operating units in an organization. On the other hand, he is interested in the physical and statistical characteristics of what can happen around them.

Reliability engineering is manifested through the maintenance plan and the results that it calls for in its execution. It is of utmost importance to point out that an operational accounting system needs four operational fronts for it to be possible: human, process, team and design; on which it is necessary to act if dynamic and long-term improvement is to be achieved. Reliability engineering should not be just a result of an improvement project but an entire organizational change.

RELIABILITY ENGINEERING PRINCIPLES

The origins of the field of reliability engineering start from a point in history where man began to use machines to work and be part of his livelihood.

A great trigger for reliability engineering has been survival, since for this to be carried out there must be reliability and security. The origins of the lawsuit are ancient, reliability engineering as a technical discipline became known along with the growth of aviation and of course the accidents that it presented, concluding that accidents are bad for business.

BASIC MATHEMATICAL CONCEPTS FOR RELIABILITY ENGINEERING

Many mathematical distributions are applied to reliability engineering that can be used for various purposes in contributing to it, including the Gaussian (normal) distribution, the logarithmic normal distribution, the Weibull distribution among others. The purpose of quantitative reliability measurements is to define the failure rate in relation to time in order to understand the quantitative aspects of failures.

PURPOSES OF RELIABILITY ENGINEERING

Reliability engineering is featured throughout the longevity and reliability of parts, products, and the system. It is about controlling risks in the best possible way. Reliability engineering incorporates a wide variety of analytical techniques specially designed to help engineers understand failure modes and patterns of change so that they can be easily identified later.

The field of reliability engineering has focused primarily on product reliability and warranty. Production organizations implement reliability engineering techniques for the purpose of production safety and reliability assurances based on machine maintenance.

Production organizations implement different reliability engineering techniques as a feasibility focus on their maintenance including different analyzes such as root cause analysis, maintenance based on improved work planning schemes, etc. These same organizations are beginning to adopt technology and cost-based design and acquisition of lifecycle strategies.

Change management plans and other advanced technical tools are made in order to control the root causes of poor reliability. A relatively basic understanding of fundamental and highly applicable methods can allow the plant reliability engineer to gain a much broader and clearer understanding of where problems are occurring.

If used properly, quantitative reliability engineering tools and methods allow reliability engineering to be applied more effectively by RCM., by removing certain conclusions involved with its application otherwise.

STAGES OF RELIABILITY ENGINEERING

Figure 1.- Stages of reliability engineering

Planning:

It is the first stage of reliability engineering, this is primarily focused on the maintenance of the process by which each and every one of the elements required to perform a task before starting the work is determined and prepared. managed. The planning process brings together all the functions related to the prevention of all the components that are required to carry out the task, before starting the complete work and detecting in this way possible failures during the process.

Programming:

The programming allows organizing and determining which tools, methods or techniques will be used for the execution process in accordance with the management of the feasibility objectives.

Execution:

In the execution phase, different applications of methods, techniques or tools are carried out to carry out the previously planned, allowing: the correction, reduction and elimination of failures within the processes in question.

MAINTENANCE

Industrial maintenance is understood to be the set of different techniques and standards established with the aim of maintaining the facilities properly as well as the industrial machinery. These types of techniques improve the performance of the equipment, in addition to amplifying the time of the good condition of the environment. Industrial maintenance is a key point for the durability and existence of an organization.

TYPES OF INDUSTRIAL MAINTENANCE

The types of maintenance internationally established and generally found in any industry are:

  • Corrective maintenance Predictive maintenance Preventive maintenance.

CORRECTIVE MAINTENANCE

Corrective industrial maintenance is one that has the purpose of correcting any type of defect that occurs in the machinery or equipment. This maintenance can be subdivided into:

  • Unplanned corrective industrial maintenance: Refers to emergency maintenance. That is, when an unforeseen event occurs and decisions must be made so that the machinery returns to its correct operation as soon as possible. Planned corrective industrial maintenance: Particularly the maintenance of which there is no evidence in advance.

Advantages of corrective maintenance:

  1. Facilities and equipment are up and running longer but underperforming. Repair costs are generally low. Greater consistency in terms of maintenance personnel workload is achieved. High specialization in security-conforming situations.

PREVENTIVE INDUSTRIAL MAINTENANCE

With regard to industrial preventive maintenance, it can be defined as a technique whose efficiency is uniquely based on the prevention of equipment failures. This method seeks to ensure that activities are always controlled so that operation is more reliable and efficient, anticipating errors before they occur.

This maintenance is useful in project management, for example. In other words, it is a good way to avoid possible future contingencies that could cost the company a high cost.

Advantages of industrial preventive maintenance:

Regarding the advantages of preventive industrial maintenance, the following should be highlighted:

  1. The risks of errors are reduced in percentage terms. Compared to other types of maintenance, the cost of maintaining it is much lower, especially in the face of unplanned failures, which are considerably reduced with this technique. Unforeseen stoppages are reduced. greater control over production and facilitates the planning of procedures and strategies.

PREDICTIVE MAINTENANCE

Lastly, and perhaps one of the most important when it comes to reliability engineering, predictive industrial maintenance stands out. In this case, there is a technique based on maintenance through periodic and objectively planned inspections in advance to determine the operability and condition of the equipment. It is produced through the knowledge of different variables, which help to discover the true state and the prevention of failures.

This type of industrial maintenance bases its effectiveness on the prevention of variables such as vibration, pressure, temperature, among others.

On the other hand, it acts as an indication of the status of the equipment. It is highly technical and requires a high level of analytical knowledge, since it generally works with highly sophisticated equipment.

Advantages of predictive industrial maintenance

  1. The operation of the machinery is more continuous and consequently the pauses in the event of an error are short to be detected early. It is very reliable, since it uses highly qualified personnel. The need for personnel is less, therefore reducing costs in The spare parts and equipment used have a high durability.

OPERATIONAL RELIABILITY TOOLS

As previously described, reliability is a methodological process which is based on different tools with the goal of allowing the different operations and machinery of the organization to be systematically evaluated, as well as risks and operational strategies.

Some reliability tools are presented below:

  • RCM2: Reliability Focused Maintenance MTA: Maintenance Task Analysis RCA: Root Cause Analysis ECO: Equipment Condition Optimization CBM: Condition Based Maintenance RCS: Reliability Focused Spare Parts OIM: Comprehensive Organization maintenance.

CONCLUSION

Today it is very important for organizations to take into account, verify and ensure the reliability of their equipment as well as their performance in all their processes.

The reliability study provides organizations with the guarantee of reduction or complete elimination of failures as well as the continuity of their operations and process. One of the fundamental keys to achieve excellence in a firm is to optimize and take care of all its areas, this practice gains strength from the need to ensure the operation in the face of demand and its production.

It is objectively understood that reliability is directly linked to maintenance since many of the tools focus on correcting, preventing and predicting different events.

This is why it is possible to ensure that an organization is completely oriented to reliability and when the institutions have a lower percentage of failures they are called successful and consequently their operating costs decrease and their utility also increases exponentially.
